GAS-BURNER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 778,252, dated December2'7, 1904. I

Application filed January 19, 1904. Serial No. 189,689.

To all whom it may concern:

Be it known that I, WILLIAM KoHN. a subject of the Emperor ofAustria-Hungary, residing at Brooklyn, in the county of Kings and Stateof New York, have invented certain new and useful Improvements inGas-Burner Attachments, of which the following is a specification, suchas will enable those skilled in the art to which it appertains to makeand use the same. I

V This invention relates to gas-burners; and the object thereof is toprovide an ordinary gas-burner fixture with electrical attachmentswhichare automatically operated to reignite the gas if the latter beaccidentally blown out or extinguished in any other way without beingfully turned ofl and with this and other objects in View the inventionconsists in an attachment for gas-burners for the purposespecified'constructed as hereinafter described The invention is fullydisclosed in the following specification, of which the accompanyingdrawings form a part, in which the separate parts of my invention aredesignated by suitable reference characters in each of the views, and inwhich' Figure 1 is a side view of a gas-burner fixture provided withmyimprovement; Fig. 2, a diagrammatic view showing the electric circuitsand showing a circuit-closer at right angles to the position shown inFig. 1 and also showing other parts of the construction; Fig. 3, a

' side view of a'detail of the construction on an enlarged scale. Y 1

In the drawings forming part of this'specification, I have shown anordinary gas-fixture which may be connected with a wall, wallbracket,chandelier, or other similar device, and said fixture comprises a pipea, having theusualvalve-casing and valve a and in the form ofconstruction shown said pipe is provided with an elbow member (0 withwhich is connected anordinary burner-tube a, provided with the usual tip6.

Connected with the pipe (0, near the casing of the valve 06 is a band 0,provided at one side with a horizontally-arranged segmental member 0 andthe handle part a of the valve a? is provided with a spring-arm 0 thefree end of which is adapted to bear on the segmental memberc of theband 0, and when the valve of is in position to cut oil the flow of gasthrough the pipe (0 the spring-arm 0 is insulated from the member 0 asshown at 0 said member being provided with insulating material at 0*.

Mounted on or connected with the upper end of the burner-tube a in anydesired manner is a disk or support d, with one side of which is securedan upwardly-directed finger d with'which is connected avertically-arranged thermostat d", which projects a predetermineddistance above the burner-tip Z) and which is bent to form lateralconvolutions, as clearly shown in Fig. 1, and which is adapted to expandand contract under the influence of heat and cold and for which purposethe said member cl is preferably made of differentmetals, such as areusually employed for such purposes. On the side of the support d withwhich the arm (Z is connected said support is provided with downwardlyand outwardly directed arms a, with which is connected an insulatedblock 6 to which is secured a contact-piece c and pivoted to the baseportion of the arms a is an upwardlydirected arm f, havingadownwardly-directed finger f adapted to make contact with the contactdevice 0 and said arm f or the part f thereof, is provided with asupplemental arm f which projects transversely of the burner-tube in adirection opposite to that of the arms 0 and which is weighted at itsend, as shown at f The upwardly-directed arm f is composed of two parts,f and f, which are insulated from each other by an intermediate part fand the finger f is formed on one of the parts, f, and the other part,f, is insulated therefrom. The part f of the arm f is provided at itsupper end with an outwardly-curved and transversely-directed member gand the part f is provided with an outwardly-curved member,-having acurved finger-piece 9 which projects transversely of the upper end ofsaid arm and over the member W, and the parts 9 and g are connected by atransversely-arranged coil of platinum. I

The band 0 is insulated from the pipe at and is also provided with abattery it, which may be placed at any desired point and which isconnected with the band 0 by a wire 7& and with the contact device a bya wire a It will be understood that the upper end of the thermostat (Zoperates, in connection with the finger g at the upper end of the arm f,to move said arm f, as hereinafter described, and the operation of thisform of construction will be readily understood from the foregoingdescription when taken in connection with the accompanying drawings.Suppose the parts to be in the position shown in Fig. 1, in whichposition the spring-arm c rests on the insulator at 0*, with which thesegmental member 0 is provided. If now the gas be turned on, the arm 0will rest on the segmental member 0 and the circuit will be completedfrom the battery through the wire it, through the contact device 0through the part f of the arm f, through the platinum coil and downthrough the other part f of said arm and through the parts (Z, a", a andthe valve a the spring-arm (t the segmental member 0 the band 0, and thewire b to the battery. This current will heat the coil g and ignite thegas, and itat any time the gas be blown out or accidentally extinguishedthe thermostat (Z will contract and the arm f will assume the positionshown in Fig. 1, and the circuit will again be completed and the gasreignited by the coil 9, and as the gas continues to burn the thermostat6Z3 will expand and'the finger f will be separated by the arm f from thecontact-piece e and the circuit will again be broken, and it will thusbe seen that the battery is only in position when it is necessary tolight or relight the gas.

In the construction shown in Fig. 2 the parts are exactly the same ashereinbefore described, except that the battery it is connected with thepipe to by a wire v and with the supplemental arm f by another wire, 2'and the band 0 is connected with the contact-piece 0 by a wire With thisform of construction the current when the gas is turned on, as shown inFig. 2, passes through the battery, through the wire 3, the part f 5 ofthe arm f, through the platinum coil 9, the part f of the arm f, andthrough the finger f the contact device 6, the wire t the band 0, thesegmental member 0 the spring-arm 0 and the valve a to the pipe (4, andthrough said pipe to the battery through the wire 2'. In this operationthe current heats the coil and the gas is ignited thereby, and when thethermostat d becomes heated the arm f operates, as hereinbeforedescribed, to break the circuit, and if at any time the gas isaccidentally blown out or accidentally extinguished without turning ofithe fiow thereof the thermostat (X will contract, and the arm f willoperate to complete the circuit, and the coil will be again heated andthe gas reignited.

This device is simple in construction and operation and perfectlyadapted to accomplish the results for which it is intended, and changesin and modifications of the construction herein described may be madewithout departing from the spirit of my invention or sacrificing itsadvantages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
